    return MaterialApp(
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final GlobalKey<ScaffoldState> _scaffoldKey = GlobalKey<ScaffoldState>();
  int _selectedMonthIndex = 0;
  int _selectedDateIndex = 0;
  int _selectedYearIndex = 0;
  bool _extendedButtons = false;
  VoidCallback _showBottomSheetCallback;

  @override
  void initState() {
    super.initState();
    _showBottomSheetCallback = _showBottomSheet;
  }

  setMonth(int index) {
    setState(() {
      _selectedMonthIndex = index;
    });
  }

  setDate(int index) {
    setState(() {
      _selectedDateIndex = index;
    });
  }

  setYear(int index) {
    setState(() {
